Definitions

  • the present invention relates to a method and a device for monitoring the integrity of a wire rope in a wire rope assembly and a wire rope assembly with such a device.
  • Wire ropes are often used to carry or tie down heavy loads and consist of a multitude of wires, usually twisted into strands or strands. These are usually in turn beaten by an insert, the so-called soul.
  • the wires can also be arranged parallel to one another without being twisted. In this case, the wires are usually pressed together with cable clamps.
  • a method for monitoring the integrity of a wire rope in a wire rope arrangement (i) the wire rope is moved past a sensor device, (ii) the sensor device is used to generate a sensor signal which indicates a magnetic interaction between the sensor device and the Sensor device characterized wire rope moved past, and (iii) based on the generated sensor signal, a measure of the integrity of the wire rope, hereinafter occasionally referred to as integrity measure, determined.
  • integrity measure a measure of the integrity of the wire rope
  • One aspect of the invention is based on the approach of using a magnet-based detection method to generate or provide information about the state of a wire rope of a wire rope arrangement, specifically preferably during normal or control operation of the wire rope arrangement.
  • the wire rope arrangement for example a cable car system or a lifting system such as a crane, can (continue to) be operated unimpaired, in particular without interruption, during a measurement of at least one variable, on the basis of which the integrity of the wire rope can be assessed.
  • the wire rope is preferably moved past a preferably stationary sensor device in such a way, for example guided in sections through or along the sensor device, that the sensor device generates a sensor signal.
  • the wire rope can be monitored essentially continuously. In this way, in particular, a high level of operational reliability is made possible.
  • the wire rope arrangement can also be operated particularly economically since no downtimes are required for maintenance purposes.
  • the sensor device can be integrated into a component of the wire rope arrangement, for example.
  • the sensor device can be designed as a component of the wire cable arrangement.
  • the sensor device can be integrated into a cable sheave or a cable drum, for example, or can be designed as such.
  • the wire rope can be moved past the sensor device in a simple manner, independently of the operating state of the wire rope arrangement, in order to generate the sensor signal.
  • the sensor signal preferably characterizes a magnetic interaction between the sensor device and the moving wire rope, in particular its strength.
  • the strength of the interaction or the corresponding sensor signal can serve as a starting point or at least as a point of reference for the integrity of the wire rope, for example for its composition, particularly in the invisible inner part of the wire rope, ie within its sheath.
  • it can be assessed whether a wire of the wire rope is broken or at least damaged.
  • the magnetic interaction can be detected using an inductance sensor, for example, which generates the corresponding sensor signal.
  • the inductance sensor is then expediently set up to measure the inductances of the cable, for example by means of a magnetic field acting on the cable, also referred to as a "test field".
  • the magnetic interaction can also be detected with a magnetic sensor, for example a Hall sensor.
  • the magnetic sensor is then expediently set up to measure the magnetic field strength of a magnetic field generated or influenced by the wire rope.
  • the integrity of the wire rope, or a measure thereof, can also be determined magnetically inductively with the aid of the sensor device.
  • the sensor device can be used to carry out a magneto-inductive measurement on the wire rope.
  • a saturation magnetization of the wire rope is preferably generated and the magnetic flux is determined through the cross section of the wire rope.
  • the sensor device can have a stray field coil or a Hall arrangement (Hall sensor) for detecting a stray field, from which the magnetic flux can in turn be derived.
  • the sensor signal can be a magnetic signal which characterizes the magnetic flux through the cross section of the wire rope.
  • a probe coil also referred to as a probe
  • the pick-up coil is preferably around a permanent magnet wound to generate the magnetic field.
  • the sensor signal can be an inductive signal that characterizes a strength of the detected change.
  • the wire rope is moved past the sensor device in a curved manner.
  • the wire rope in the area of the sensor device i. H. in a section adjacent to the sensor device.
  • the wire rope can be guided over a rope pulley in the area of the sensor device.
  • the wire rope can curve around the sensor device at least in sections, for example if the sensor device is integrated into the cable pulley or is therefore designed as such.
  • the curvature of the wire rope makes it possible to determine information regarding the integrity of the wire rope in a particularly loaded state, i. H. at a point of particularly high stress. Since it can be assumed that the integrity of the rope is impaired precisely at such points of heavy loading, the risk of the overall condition of the wire rope being incorrectly assessed, in particular as too good, can at least be reduced.
  • a position of the wire rope relative to the sensor device is detected and used as a basis for determining the measure of the integrity of the wire rope.
  • a position of the wire rope relative to the sensor device is preferably defined by the section that is currently located in the area of the sensor device is or is advanced to it. i.e. the position of the wire rope relative to the sensor device can change when the wire rope is moved past the sensor device.
  • the detected position of the wire rope relative to the sensor device allows a particularly differentiated assessment of the state of the wire rope.
  • the detected position of the wire rope relative to the sensor device can be used to determine how often a section of the wire rope currently detected by the sensor device has already run over a wire rope bearing, such as a sheave, and has been bent or bent and thus particularly stressed.
  • a wire rope bearing such as a sheave
  • conclusions can be drawn about the state of the wire rope from the number of corresponding changes in curvature or bending, as well as from the magnetic interaction between the sensor device and the wire rope.
  • the wire rope integrity can be assessed even more comprehensively, for example by combining, for example offsetting, the determined number of curvature or bending changes with a strength of the magnetic interaction characterized by the sensor signal.
  • the determined integrity measure can also be assigned to a section of the wire rope by detecting the position of the wire rope.
  • a change in the magnetic interaction over time can be detected, in particular tracked, and used as a basis for determining the integrity measure.
  • the position of the wire rope relative to the sensor device can be detected, for example, using a position encoder of a wire rope bearing, in particular a sheave.
  • a position encoder can, for example, record an acceleration, a (rotational) speed and/or an orientation or position of the wire rope bearing. The number of revolutions of the wire rope bearing thus detected can then be transferred to the position of the wire rope relative to the sensor device.
  • the sensor device is designed as a wire rope bearing.
  • the acceleration, the (rotational) speed and/or the orientation or position of the sensor device can be recorded and used as a basis for determining the measure of the integrity of the wire rope.
  • the sensor signal generated in particular the measure determined for the integrity of the wire rope, is assigned to the detected position of the wire rope relative to the sensor device.
  • the section of the wire rope currently being moved past the sensor device can be assigned to the generated sensor signal. This makes it possible to understand, for example, how often the wire rope or the section was moved past the sensor device, i. H. how often the integrity measure has already been determined for this section.
  • the integrity measure can be linked to a usage period or usage cycles. This allows a particularly precise assessment of the condition of the wire rope.
  • the measure of the integrity of the wire rope can also be determined on the basis of the assignment of the sensor signal to the position of the wire rope relative to the sensor device.
  • the number of bends in the area of a wire rope bearing is determined based on the position of the wire rope and, in addition to the sensor signal, is used as a basis for determining the integrity measure.
  • mechanical wear of the wire rope can be taken into account, even if this has little or no effect on the sensor signal.
  • a prognosis for the development of the integrity of the wire rope is made on the basis of the measure determined for the integrity of the wire rope. For example, it can be estimated for how many operating cycles the wire rope can still be used without hesitation, ie for example without its integrity meeting a specified replacement criterion.
  • a number of the still acceptable bending cycles of the wire rope for example occurring when being guided over a sheave, can be predicted.
  • spare parts can thus be ordered and/or maintenance work can be planned at an early stage.
  • the determined measure of the integrity of the wire rope is recorded, i. H. a history or a progression of the integrity measure is recorded.
  • a particularly differentiated and precise prognosis can be made on the basis of this log or the history.
  • a check is carried out, in particular in an automated manner, as to whether the determined measure of the integrity of the wire rope satisfies an exchange criterion.
  • An exchange signal is preferably output based on the result of the test. In this case, it is expediently checked whether the ascertained measure of integrity reaches or falls below a predetermined integrity threshold value. If this is the case, the output signal, for example an acoustic and/or visual warning signal, can be output. This allows timely decommissioning of the wireline assembly, i. H. for example before the wire rope breaks completely, in a particularly reliable manner.
  • the exchange signal in particular as an acoustic and/or visual warning signal, can be output to a user, for example to operating or maintenance personnel of the cable arrangement.
  • the exchange signal in particular as a digital or control signal, can be output to a control device which is set up to control the wire cable arrangement. This allows the wire rope arrangement to be shut down automatically if necessary.
  • the measure of the integrity of the wire rope is determined using artificial intelligence.
  • the artificial intelligence such as a neural network, is or will preferably be trained to recognize the generated sensor signal, in particular changes in the Sensor signal to compare with a specified sensor signal and to draw conclusions about the wire rope integrity from the comparison.
  • the artificial intelligence can be or will be trained, for example, by machine learning. With the help of artificial intelligence, patterns in the sensor signal, for example patterns that occur over time, can be recognized and the determination of the integrity measure can be used as a basis. In this way, the information contained in the sensor signal, in particular in its course over time, can be used particularly efficiently and comprehensively. This also makes it possible to increase the meaningfulness of the integrity measure.
  • the determined measure of the integrity of the wire rope is provided via an interface of the sensor device in a network.
  • the integrity measure can, for example, be communicated via the Internet of Things or can be called up by devices that are connected to this network. It is thus possible for these devices, for example, to influence the operation of the wire rope arrangement and/or to further process the information provided and to initiate processes based thereon. It is conceivable, for example, that forecasts about the cable requirements and/or maintenance plans can be created in this way. This allows a far-reaching and efficient use of the determined information related to the wire rope.
  • the wire rope arrangement is operated, in particular automatically, depending on the determined measure of the integrity of the wire rope.
  • the wire rope arrangement can be controlled on the basis of the determined measure of integrity.
  • the operation of the cable assembly can be stopped or at least be interrupted if the determined integrity measure meets a predetermined exchange criterion.
  • the determined integrity measure can be processed by a control device for controlling a cable drive and the control can be used as a basis.
  • At least one sensor unit of the sensor device configured to generate the sensor signal moves relative to a stationary component of the wire rope arrangement.
  • the at least one sensor unit can, for example, rotate relative to a wire rope bearing, in particular a rope pulley.
  • the at least one sensor unit can in particular rotate relative to the sensor device if the sensor unit is designed as a pulley.
  • the sensor device embodied as a cable pulley can have a plurality of sensor units arranged along the circumference of the cable pulley, each of which is mounted such that it can rotate about an axis of rotation relative to the cable pulley.
  • the sensor units preferably each include a means for generating a magnetic field and thus the magnetic interaction between the sensor device and the wire rope, and an inductance or magnetic field sensor for detecting the interaction and generating the sensor signal.
  • the sensor units can be rotated actively or passively, for For example, by gravity with eccentric mounting around the axis of rotation or by a corresponding drive, such as a gear for translating the rotary movement of the cable pulley to each of the sensor units.
  • a device for monitoring the integrity of a wire rope in a wire rope arrangement has a sensor device that is set up to generate a sensor signal that characterizes a magnetic interaction between the sensor device and the wire rope moved past the sensor device.
  • the wire rope arrangement also has a stationary component in which the sensor device is integrated. It is expedient here for the sensor device to be designed as a component part of the cable arrangement, i. H. the component embodies.
  • a stationary component within the meaning of the invention is in particular a stationary component that does not move in a translatory manner during normal operation of the cable arrangement. However, it cannot be ruled out that the component at least partially performs a different movement, for example rotating.
  • the device has a control device which is set up to determine a measure of the integrity of the wire rope on the basis of the generated sensor signal.
  • the stationary component is a wire rope bearing.
